Abstract: Field e~perim~nt was conducted at H. R. S. Mond~uri, BCKV, WB during 1998-2000 to study the effect of spacing and seed Corm size on yield of elephant foot yam, grown as mter crop in an 18 yrs old coconut ( cv.-ECT) garden and to study the effect if inter crop o.n the economic~ of the cropping system . Among the five different spacings and two corm sizes, yield at 40 x 40 Cm spacing with 500g corm size (71.45 kg/ 9.6m2) was the best for elephant foot yam, grown as intercrop in coconut. It was Observed that P 1S2 (40 x 40 cm, 500 g) adding the fixed cost for other component crop, recorded maximum cost of cultivation (Rs. 92,891 /-), maximum gross return (Rs. 1,38,328.L-) and net return (Rs. 45,367/-). Maximum benefit: cost ratio (0.85) was Obsreved in P1s4 (70 x 70 cm, 300 g) combination..
